Just thought if give my thoughts on this as everyone is calling him bad. I don't think he is awful but there are a few things is upgrade.
1. His basic reflexor shot (forward triangle) I think maybe add kickback to this like on Ratchest combustion gun (this one is very debatable since it has a fairly long range) 2. Up his ap gain a bit but not a lot to me he does not build ap as sliw much as everyone is making it he does. 3. His needle lazer I'd say give a bit more distance. 4. Gyro buster give a bit longer duration(not much longer it gets 5ap a shot landed which is good if you use it when everyone is in a group in FFA). 5.Make his level 2 go off a bit faster it has slow start up but is easy to see coming(in my opionion it has pretty good range though)
Those are about it for me. Feel free to share what you agree or disagree with and any suggestions.
